Writes Stuhl,“The age of automation – that art of worker-less factories which has industrial management crackling these days – is coming close to broadcasting,” announced Broadcasting magazine in 1954. Just as it is today, automation to radio practitioners in the 1950s was a daunting complex of threats and promises around technology, labor, and artistry. But it was also, more simply, a property of magnetic tape recording. Radio automation began as the technique of embedding “cue tones” in taped sound and configuring tape players to start or stop upon detecting them. From the ’50s into the era of syndication by satellite, almost every automation system used the same frequency for these tones: 25 Hz.

25 Hz splices together audio samples from a span of 1951 to present, casting radio automation amid characters from the sonic arts and popular culture in a historical drama. A 25 Hz “cue tone” punctuates each splice, inverting the automation system’s goal of seamlessly executing a programmed sequence. Re-sonifying those seams from within radio, the piece aims to open automation up as more than an industrial object – as a peculiar, emotionally charged, and passionately countered dream that has perhaps had something in common with avant-garde legacies in post-WWII America.”
